...ere localpart contains a quoted @: dovecot-2.2.33.2-reverse-domaincut.patch 2. Fully decode local part on receipt in LMTP, and re-encode when proxying. This fixes the issue where quoted local quotes are stripped on proxy, preventing successful proxying, and some director hashing problems (exposes str_append_maybe_escape in message-address.h, some logging is still inconsistent, though, but would require a major rework): dovecot-2.2.33.2-quoted-local-proxy.patch -- David Zambonini -------------- next part -------------- --- dovecot-2.2.33.2/src/lib-mail/message-address.c 2017-10-05 18:10:44.000000000 +0100 +++ do...

The third problem is then re-encoding the username in the envelope recipient when proxying, which was not done at all. I've added a function lmtp_client_rfc822_escape_address(), which is similar to str_append_maybe_escape() to escape the address at protocol time in lmtp_client_send_rcpts() [src/lib-smtp/lmtp-client.c], although I suspect it should be done earlier, this is just a working proof. The other reason I don't believe this patch is production quality is that I have not examined any interaction between t...
